The pedals 2 and 3 are also intended for use in the saine Way that the. pedal 4 is. To y i such end said pedals 2 and 3 are -provided with apertures2FL and 3a, respectively,` into which pins similar to the pin 5 maybe inserted. Suchpins are'not shown hereinv as it is intended that when they are not used they Will be put aside in somefconvenientY place.
